The Spread Collision: When LLM Output Silently Overwrites Your Workflow State

说明与用途

LLM 输出中的 spread 操作符会悄悄覆盖元数据和真实数据，导致工作流中的数据完整性丢失。

问题

A spread operator used to merge LLM‑generated JSON into an existing API envelope silently overwrites metadata and real data, causing silent corruption of workflow state.

结果

The spread collision caused silent data corruption in the workflow, leading to loss of provenance metadata and product information without any runtime errors.

工作流

• Read product spreadsheet
• Build multilingual listing prompt per row
• Call chat‑completions endpoint
• Parse model JSON reply
• Merge parsed JSON into item using spread operator
• Write results to spreadsheet

证据

This one spread operator can corrupt your data without ever throwing an error.
